This is my code.
Please check it where it is giving runtime exception.
I wrote a piece of code to solve this problem.
I keep getting NZEC(runtime error), but I can't find which part of the code can cause any Exception since it only involves simple arithmetic computation (there should be no chance of divided by zero).
The logic of the code doesn't matter, and I just wonder where the exception could be hiding.
Any one can spot any bug? Thanks.

while (t-- > 0) // while loop

int sum = 0;
int n = Integer.parseInt(br.readLine()); //number of elements in array
int arr[] = new int[n];
for (int i = 0; i < n; i++)
arr[i] = sc.nextInt();
for (int i = 0; i < n; i++)
sum += arr[i];
if (sum % n == 0) //if divisible by n,print n
System.out.println(n);
else
System.out.println(n - 1);
}
}
}
